Undocumented APIs
Thank you for submitting your application to Apple’s App Store. Unfortunately, your application cannot be added to the App Store because it is using an undocumented API, AppSupport, which as outlined in the iPhone SDK Agreement section 3.3.1 is prohibited:
“3.3.1 Applications may only use Published APIs in the manner prescribed by Apple and must not use or call any unpublished or private APIs. “
A similar issue is effecting me. The problem is that I _wasn’t_ using a private API. I licensed (and paid for) a functional equivalent of a private API, totally above board. Pointed the reviewer to a website that corroborated this, but my app is still stuck in review. Exact same feature was in the accepted 1.0 release of the app, ran into trouble on the revision.
